Abstract: A coordinate input device (e.g. mouse-like device or cursor-like device) includes an outer housing which is movable between a first position adapted for use by right-handed users, and a second position adapted for use by left-handed users. In such a manner, the coordinate input device is easily utilized by both right and left-handed users. In certain embodiments, a rotatable thumb or finger wheel may be provided in the coordinate input device for manipulation by the user in order to adjust a parameter of an image being written/drawn on a corresponding display screen by the coordinate input device.

Abstract: A two-handed game controller has a single dual analog/digital x-y directional pad mounted on the top which can perform either analog or digital functions. A mode switch on the controller allows an operator to select either analog or digital control settings. The controller also has a button grouping located within a concave recess. Each button within the recess has a downward slanting top maintained at an elevation a specified distance from the controller, thereby allowing for easy actuation by a gliding, rolling or sliding motion of a user's thumb or finger. The controller also has semicircular sides and 3-dimensionally tapered hand-grips, facilitating grip from virtually any size hand, from child to adult. Digital triggers are mounted on both the top and bottom of the controller and are configured to perform the same functions, allowing table-top use. Furthermore, the controller has a tripod-like structure with slip-resistant grips providing stability on a table-top surface.
